“…Waste fruits may also represent a substrate for bioethanol production. For example, banana waste or rotten banana, peels and sub-quality fruits have been extensively studied as substrates for bioethanol production (Graefe et al, 2011;Oberoi et al, 2011;Hossain et al, 2011;Arumugam and Manikandan, 2011;Gonçalves Filho et al, 2013;Bello et al, 2014).…”

“…Banana peel has been used as traditional medicine for treatment of various ailments such as burn wound, anaemia, diarrhoea, ulcers, inflammation, diabetes, cough, snakebite and excess menstruation (Fries et al, ; Gore and Akolekar, ; Kumar et al, ; Pereira and Maraschin, ). Recently, banana peel has also been utilized to make banana peel flour (Rebello et al, ), as an adsorbent for water purification (Pathak et al, ), to extract pectin for food application (Oliveira et al, ) and to produce ethanol (Meena et al, ; Oberoi et al, ).…”

A large quantity of banana peel is generated annually and is considered as waste with low value. This study aimed to optimize five extraction parameters; including ultrasonic temperature, time and power, as well as acetone concentration and sample to solvent ratio, for maximum recovery of phenolic compounds, flavonoids, proanthocyanidins and antioxidant properties from banana (Musa cavendish) peel using response surface methodology. The results showed that recovery yields of phenolic compounds, flavonoids, proanthocyanidins and antioxidant properties were affected by the extraction parameters; of which the acetone concentration had the greatest effect. Optimal extraction conditions were found to be at ultrasonic temperature of 30°C, ultrasonic time of 5 min, ultrasonic power of 150 W, sample to solvent ratio of 8:100 g/mL and acetone concentration of 60%. Under these optimal conditions, 23.49 mg of phenolic compounds, 39.46 mg of flavonoids and 13.11 mg of proanthocyanidins could be extracted from 1 g of banana (M. cavendish) peel. Practical applications Banana peel known as waste is generated in a big quantity with limited utilization. Therefore, it is necessary to utilize this by‐product for adding value to food industry. This study was designed to establish a simple, effective extraction method for maximum recovery of phenolic compounds from banana peel. Findings from this study can be used for further isolation and purification of phenolic compounds from banana peel for subsequent application in nutraceutical and pharmaceutical industry.

“…The purpose of the pretreatment was to remove lignin and/or hemicellulose, to disrupt the crystalline structure of cellulose, and to increase the porosity of the material, making it more accessible to enzyme attack [21]. The compositions of miscanthus before and after dilute sulfuric acid pretreatment are given in Table 5.…”

Abstract:In this study, an innovative green biorefinery system was successfully developed to process the green biomass into multiple biofuels and bioproducts. In particular, fresh giant miscanthus was separated into a solid stream (press cake) and a liquid stream (press juice) using a screw press. The juice was used to cultivate microalga Chlorella vulgaris, which was further thermochemically converted via thermogravimetry analysis (TGA) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) analysis, resulting in an approximately 80% conversion. In addition, the solid cake of miscanthus was pretreated with dilute sulfuric acid and used as the feedstock for bioethanol production. The results showed that the miscanthus juice could be a highly nutritious source for microalgae that are a promising feedstock for biofuels. The highest cell density was observed in the 15% juice medium. Sugars released from the miscanthus cake were efficiently fermented to ethanol using Saccharomyces cerevisiae through a simultaneous saccharification and fermentation (SSF) process, with 88.4% of the theoretical yield.
